Hi everybody,
I wonder if it is possible for the STM32F407 to reboot itself into Bootloader mode ?I am thinking of doing :- control NRST with a GPIO in OpenDrain mode (GPIO has no internal pull resistor, because NRST has internal pull up already)- just add a 100nF capa on NRST signal to stabilise it- fix BOOT1 to 0 with external pull-down of 10k- external pull-down 10k on BOOT0 for normal boot operation on Internal Flash- let another GPIO control BOOT0 through a RC or another method to be sure the BOOT0 signal will be sampled to high when reset occur and so STM32F4 boot in Bootloader modeThis seems very risky, so I would like to have comment from you, and specially if you already tried this kind of setup...Thanks #boot0-dfu-stm32f42014-06-30 08:40 PM

Dear CLive1,
what would be this forum without you !!! Thanks a lot, I made some search before posting, but not in the right sub-forum... As I understand in your post , there is a way to reboot in bootloader mode with software only, so without externally manipulating BOOT0/1. That is perfect ;)
